A new Standard and a new name for 2020/2021 Wi-Fi 6e

Here are our thoughts on the standard, its timing and use for our Clients in 2020 and out to 2021.

  • Wi-Fi 6 is using all existing 2.4 and 5Ghz Standard spectrum. Wi-Fi 6e is adding the next 1.2 ghz at the 6 ghz spectrum.
  • You will need Wi-Fi 6 devices to allow any connection to them and you will need new hardware to support the 6ghz range.
  • Our estimation based on 20 plus years of Wi-Fi is this will take at least 4 years for useful deployment for the general population and 2 years for the early adopter market. It may come quicker for specific use cases such as inbuilding backhaul or low latency devices.
  • It also may come in sooner for newer IOT devices built for specific needs such as door locks, smoke detectors, but pricing is going to be a major issue as always for these low-cost devices.
  • With the increased channels we should see a benefit to less congestion and issues of connectivity between devices.
  • We have not read any detail on power consumption differences at this time.
  • The branding of Wi-Fi 6e is more about inclusionary of the 6ghz to leverage on the name people are already comfortable with “Wi-Fi”.
  • The United States will have more available spectrum than Europe at this time so the standards for products will be difficult for international usage. As an example a user in New York may find that there devices need adjustments (less bands available) when traveling to Paris.
All in all this is a good thing for users and relieving congestion on the Wi-Fi networks, the question now is timing and execution.

Current Wi-Fi Challenges

A Wi-Fi network needs to be designed to address the growing demand for the high volume and diversity of connected devices and services we have gone from less that 10 devices per AP beyond a hundred.
This affects user experience. Help is on the way.In the real world, the problem isn't how fast Wi-Fi can go, but whether the Wi-Fi network has enough capacity to handle the expanding population of client and IOT devices, as well as numerous users with diverse networking needs.
Today, mobile devices are robust enough to replace more expensive laptops, so Wi-Fi has had to catch up. The issues facing next generation Wi-Fi systems involve degradation to system efficiency due to a growing density of Wi-Fi clients and network traffic with lots of small data frames, such as Voice over Wi-Fi (VoWiFi).
With an ever-growing number of devices using Wi-Fi, along with the emergence of the Internet of Things (IoT), Wi-Fi networks need to do a better job of managing today's wireless environments, increased data traffic, and a diverse mix of applications and services with differing quality of service (QoS) requirements.

The next Wi-Fi standard - 802.11ax Now called Wi-Fi 6.

Past 802.11 amendments have delivered higher data rates and wider channels but haven't addressed efficiency challenges in wi-fi networks. Wi-Fi traffic jams are still inevitable. Despite the higher data rates and 40/80/160 MHz channels used by 802.11n/ac radios, multiple factors create traffic congestion in 802.11 networks. The 802.11ax (WIFI 6) amendment focuses on high efficiency with technology to address the inefficient use of the Wi-Fi medium.
The 802.11ax (WIFI 6) family of access points are designed for high performance and high efficiency environments using latest in wifi standards, the latest in ethernet standards, and Aerohive's proven software defined Wi-Fi architecture.

The 802.11ax (WIFI 6) Vision - More than Just Speeds and Feeds.

The next Wi-Fi standard, 802.11ax (WIFI 6), is fast approaching IT HAS ARRIVE (New APs and phones /devices are shipping in January 2020- and it's not just about faster Wi-Fi speeds.
The changes in the 802.11ax (WIFI 6) standard will improve the way Wi-Fi networks work by leveraging technology that substantially improves capacity, provides better coverage, and even reduces congestion, resulting in a far better user experience overall. It's Wi-Fi for the real world.
The 802.11ax (WIFI 6) standard is designed to increase capacity by up to four times. This will provide benefits in both the 2.4 GHz and 5 GHz bands in a variety of environments including enterprises, schools, retail businesses, hotspots, airports, and even the home.

Things You Need to Know about 802.11ax (WIFI 6)

It's a Wi-Fi paradigm shift: 802.11ax (WIFI 6) is not just about better throughput. The 802.11ax (WIFI 6) standard will substantially improve capacity, provide better coverage, and reduce congestion in Wi-Fi networks.
Installing in early 2020, You won't need to rip-and-replace your existing Wi-Fi installations: If you expect your next upgrade to last 5+ years, it only makes sense to upgrade with 802.11ax (WIFI 6) technology. Additionally, if your organization still has legacy 802.11a/b/g/n APs deployed, go ahead and consider an enterprise-wide upgrade.

Look forward to a improved backward compatibility: Unlike the 802.11ac standard, 802.11ax (WIFI 6) supports both 2.4 and 5 GHz wireless devices, so 802.11n (and potentially 802.11g and 802.11b) devices will be able to run on 802.11ax (WIFI 6) Wi-Fi networks.
Your smart home is a high-density Wi-Fi environment: The primary use case defined for 802.11ax (WIFI 6) is high density network environments. But high-density doesn't just mean stadiums, hospitals, and warehouses. Today's smart homes quickly become "high density" with 20 or more wireless devices connecting to a home Wi-Fi network.

Wi-Fi security will be better. Although the 802.11ax (WIFI 6) standard itself doesn't specify any new security enhancements or requirements, it does require WPA3 security as a prerequisite. As a result, 802.11ax (WIFI 6) devices will include the latest security design features and capabilities to address modern threats that did not exist just a few years ago when 802.11ac was released.

No qualms about higher data speeds either. 802.11ax (WIFI 6) will support 1024-QAM and new modulation and coding schemes (MCS) that define higher data rates providing a potential 20 percent increase in data throughput over 256-QAM (introduced in 802.11ac). No more Obsessing over spatial reuse.

MU-MIMO enhancements are coming. Several enhancements to MU-MIMO proposed in 802.11ax (WIFI 6) include grouping sounding frames, data frames, and other frames among multiple users to reduce overhead and increase uplink response time.

RU ready for simultaneous multi-user Wi-Fi access? We can help you decide and take you through the steps, just drop us a note.

Happy Belated Birthday Wifi 1997- 2019

Wi-Fi as a product name and standard that is 20 years old this weekend. I started in Wifi well before this, when it was just called 802.11 by proxim and aeronet (later att and Cisco). In those days the hardware clients available did not necessarily work well with the competing access points. Today you can buy almost any Access point and have it connect to Wi-Fi. This is due to the hard work that both eTribeca and many other deployment organizations put countless hours to make Wifi Seamless in both home and enterprise alike.

Imagine in the past you needed special drivers on your operating system and perhaps implementations like CCX from Cisco to seamlessly run from one location to another even in the same building. Today basic Wi-Fi is taken for granted but we still have a long way to go. The latest standard 802.11ax is the first step and we may take another 5 years from now to see the next major interoperability in WiFi systems increase seamlessly work.

The new iPhone 11 as well as other manufacturers have started to add the .AX standard and CBRS capability. I have been advising those making new client purchases to embrace these technologies not for what they can use today but where it will be in 2022 and beyond cBRS is a 3.5 GHz capability that I hope to see turned on for in building by both the carriers and companies like ours by manufacturers like Ruckus.

Imagine being able to take a phone call or video call from outside and walk right through the hospital without loss of signal or connection. Other than the cool factor maybe this is what can be used in telemedicine and other critical services. (eTribeca) puts these technologies to be together in reliable and unique ways for both small and medium size as well as Enterprise clients. I think the early adopter mentality this leap forward in technology and has more merit as we coming to 2020 and needs the discussion to be started soon as possible.
